This is the original version that was demonetized on my YouTube channel.

This is the MP7 firing video promised in the cleaning video on my main YouTube channel. It's mostly firing but there's a bit at the very end that should be of interest to gun nerds! Please let me know if you're one of the nerds who appreciated watching that little analysis, thanks!

I posted this here a few weeks ago and it was unceremoniously deleted within 3 hours. I see there are other videos here on the topic so I'll try again.

This is a 2020 video from my YouTube channel: Here's a quick look at an Ultimax 100 machine gun parts set that I recently bought from a friend. These things used to be fairly reasonable but lately they're going for as much as $6,000!! As I said in the video, just the 100-round drum magazines are going for around $3,000. Crazy times we're in, folks! Kore Essentials Gun Belts: https://www.koreessentials.com/collections/gun-belts

An introductory look at what it takes to build an Uzi submachine gun from a chopped-up parts kit.

The second in the series on this gun I made in the early days of the plan...uh...pandemic.

I started designing the Diabolus rifle around 2018 and showed it off at SHOT 2020. The gun is basically an AR-18/AR-180 that's aluminum instead of stamped steel, and it uses STANDARD AR-15 bolt heads, barrel extensions and firing pins, as well as all fire control parts. Finally, today, on the 25th anniversary of the founding of Serbu Firearms, Inc. (6/21/96), do I finally get everything done in order to get it to fire semi-automatically!

Here's more of the Diabolus rifle including range time, high-speed video, and some looks inside. The Diabolus is sort of a hybrid between an Armalite AR-18 and an AR-15. It uses the bolt carrier riding on rods like the AR-18, but uses the cam pin in the vertical position like the AR-15. Uses standard AR-15 bolts, barrel extensions, firing pins and fire control parts. It has a unique gas system with a piston just forward of the trunnion, fed from a gas tube connected to a standard AR-15 gas block.

Here we weld together and build an Uzi submachine gun from a parts kit.

What did you do during the COVID-19 lockdown? I never really got locked down, but I did have extra free time from a lot of my usual activities getting cancelled. So I made a new gun...

This is a review of the ROF Submachine Gun which I built back in 1999. This is the first time I've taken it completely apart since then, and you get to see what's inside! Plus you'll hear some of my thoughts on why I designed things the way I did, plus some other commentary that you may find informative, entertaining or shocking!
